Just three weeks after Shaw's arrival, United sold Patrice Evra, the France international who had been the club's first-choice left-back for eight years.

To succeed Evra, who was also a big influence in the dressing room, seems a tall order for a player who has only just turned 19, but Shaw does not seem fazed at all.

"I don't feel any pressure to come in for Evra," Shaw said on the eve of United's first pre-season game against the Los Angeles Galaxy.

"He has been great for the club for the last 10 years and I hope I can carry that on. I will just try to focus on my own game, what I do on the pitch. I'm looking forward to trying to impress the new gaffer.''

Shaw's arrival at United had been something of a surprise given that he had supported Chelsea, who were also interested in his signature, since he was young.
